Specification of Letters Patent.

Patented Dec. 13, rear.

Application filed November 29, 1919. Serial Ito. earner.

To all whom it may concern Be it known that I, Gnoncn A. BoNnLnI, acitizen of the United States, residing at Kingman, Mohave county, andState of Arinone, have invented certain new and useful Improvements inPower-Transmission Attachments for Automobiles, of which the followingis a specification, reference being had therein to the accompanyingdrawing.

My invention relates to improvements in power transmission attachmentsfor automobiles, and my object is to provide a mechanism, which may bereadily, detachably secured to the automobile, whereby the motor of theautomobile may be utilized for the operation of tools or machines suchas road making devices or mowing machines, which travel with theautomobile; or, stationary machines or tools such as saws, churns,pumps, grindstones and the like. A further object being to provide meansfor such mechanism. whereby the tool or machine operated by theautomobile motor may be controlled independently of the motor control.

Referring to the drawing- ]Figure l is a side elevation of a mechanismembodying my improvements.

Fig. 2 is a plan view of a mechanism embodymg my improvements.

The numeral 5 designates the chassis of an automobile, 6 the enginecase, 7 the hood and 8 the engine shaft, all of which may be of ordinaryconstruction.

To the chassis l detachably secure the rails 9 which project forwardlybeyond and at each side of the automobile, and to the rails 99 I attacha frame 10, which rails and frame constitute a support for my improvedmechanism for driving extraneous tools or machines, and which frame maybe utilized to support the tool or machine in order that the tool ormachine may be carried by or advanced with the automobile in its work.

lln my drawing 1 show the tool 11 as a rotary saw, supported in bearings12, carried by the frame 10, but in no sense do ll mean to limit myselfto such a tool, or to a tool or machine carried by the frame 10, asobviously the automobile may be stationed adjacent any power drivenmachine or tool and its motor connected therewith by my powertransmission attachment.

llhe driven shaft 13 of my attachment comprises a universal joint 14,whereby I am enabled to readily connect the motor shaft, 8, with toolsor machines alined with the motor shaft, as for instance a sickle bar ofa mowing machine operating next the ground, or to a machine laterallynon-alined with the motor shaft.

Connected with the driven shaft there is a transmission 15, having acontrol lever 15, whereby to control the speed and direction of rotationof the driven shaft independently of the motor shaft, and whichtransmission is provided with a clutch 16, whereby the driven shaft mayat will be connected or disconnected with the motor-shaft. In my drawing1 show the driven'shaft of my at tachment as being arranged forconnection with the front, or crank end of the engine shaft, as by meansof a socket 17 having a pin and slot connection 18 with the engineshaft. In this arrangement I provide my attachment with means forcranking the motor comprising a gear wheel 19 slidably mounted on thedriven shaft 18, having a shifting lever 20 and a gear wheel 21,supported on a shaft 22 in the frame 10, and a crank 23 for turning theshaft 22.

By means of the peculiar construction of my attachment the automobilefor its common employment may be completely stripped of all the parts ofmy attachment, and when it is desired to employ the automobile motor tooperate other tools or machines, the auto mobile is driven to the toolor machine, the rails 9 secured to the chassis, and the frame 10supporting the transmission and other controls, is secured to the railsand the shaft l3'connecte'd with the tool. The motor is then set inmotion and the tool controlled through the clutch 16 and thetransmission 15.

Having thus described my invention what I claim as new and desire tohave secured to me by the grant of LettersPatent, is

1. A power transmission attachment for automobiles comprising a chassis;forwardly projecting rails detachably secured to the sides of saidchassis; a frame secured to said rails; a driven shaft mounted in saidframe and arranged for connection with the engine shaft; and means forcranking the engine shaft comprising a gear member slidably mounted onsaid driven shaft and an engaging crank and gear carried by said frame.

2. A power transmission attachment for automobiles comprising a chassis;forwardly projecting rails detachably secured to the sides of saidchassis; a frame secured to said rails; a driven shaft having aclutchcontrolled transmission and mounted in said frame and arranged forconnection with the engine shaft; and means for cranking the engineshaft comprising a gear member slidably mounted on said driven shaft andan engaging crank and gear carried by said frame.

3. A power transmission attachment for automobiles comprising a chassis;forwardly projecting rails detachably secured to the sides of saidchassis; a frame secured to said rails; a driven shaft embodying auniversal joint and a clutch-controlled transmission mounted in saidframe and arranged for connection with the engine shaft; and means forcranking the en ine shaft comprising a gear member slida 1y mounted onsaid driven shaft and an engaging crank and gear carried by said frame.

4. A power transmission attachment for automobiles comprising a chassis;a frame detachably secured to said chassis; a driven shaft embod ing auniversal joint and a clutch-contro led transmission mounted in saidframe and arranged for connection with the engine shaft; and means forcranking the engine shaft comprising a gear member slidably mounted onsaid driven shaft and an engaging crank and gear carried by said frame.

In testimony whereof I hereunto affix my signature.
